+===== Module 2. Classical Integration and Low-Level Communication =====
+This block covers foundational distributed communication techniques and older but historically important integration models.
+  * [[tanszek:oktatas:iss_t:object_request_broker|Object Request Broker (CORBA)]] - Classical middleware and distributed object communication with ORB, IDL, and broker-based invocation.
+  * [[tanszek:oktatas:iss_t:integration_based_on_tcp_ip_sockets|Integration based on TCP/IP Sockets]] - Low-level point-to-point communication and the basic mechanics of network integration.
+    * [[tanszek:oktatas:iss_t:java_example_for_blocking_and_non-blocking_socket|Java example for Blocking and Non-Blocking Socket]] - Practical Java socket example for synchronous and asynchronous communication patterns.
+    * [[tanszek:oktatas:iss_t:python_example_for_blocking_and_non-blocking_socket|Python example for Blocking and Non-Blocking Socket]] - Practical Python socket example for blocking and non-blocking communication.
+    * [[tanszek:oktatas:iss_t:socket_exercises|Socket Exercises]] - Practice tasks for reinforcing socket-based communication.
+    * [[tanszek:oktatas:iss_t:http_server|HTTP server]] - Example page connecting socket-level understanding with a simple application protocol.
+  * [[tanszek:oktatas:iss_t:java_-_remote_method_invocation|Java - Remote Method Invocation]] - Java-specific remote invocation model, useful for understanding language-bound distributed calls.
+    * Original paper: [[https://pdos.csail.mit.edu/archive/6.824-2009/papers/waldo-rmi.pdf|A Note on Distributed Computing]]
+    * Oracle tutorial: [[http://docs.oracle.com/javase/tutorial/rmi/index.html|Java RMI Tutorial]]
+    * [[tanszek:oktatas:iss_t:group_chat|Group chat]] - Applied example built around the RMI communication model.
+    * [[tanszek:oktatas:iss_t:group_chat_-_nodejs|Group chat - NodeJs]] - Comparative communication example using Node.js.
+  * [[tanszek:oktatas:iss_t:integration_based_on_rpc_remote_process_call|Integration based on RPC Remote Process Call]] - Conceptual transition from raw communication to call-oriented distributed interaction.
+    * [[tanszek:oktatas:iss_t:xml-rpc|XML-RPC example]] - Structured RPC example using XML-based message exchange.
+===== Module 3. Modern APIs, Contracts, and Remote Calls =====
+These topics focus on structured service contracts, modern remote procedure calls, and API-oriented integration.
+  * [[tanszek:oktatas:iss_t:modern_data_integration_based_on_protocol_buffer|Modern Data Integration based on Protocol Buffer]] - Schema-driven data exchange and compact cross-language serialization.
+  * [[tanszek:oktatas:iss_t:grpc|Google's modern remote procedure call technique]] - Modern RPC based on Protocol Buffers and service contracts.

+  * [[tanszek:oktatas:iss_t:graphql_integration|graphQL integration]] - Query-driven API design that lets clients request exactly the data they need.
+===== Module 4. Deployment and Runtime Integration =====
+Integration is not only about protocols. It also depends on packaging, deployment, runtime isolation, and service-to-service topology.
+  * [[tanszek:oktatas:iss_t:docker_integration_techniques|Docker integration techniques]] - Container-based integration and deployment as a practical runtime foundation.
+    * [[tanszek:oktatas:iss_t:docker|Simple multi container example]] - Hands-on example of multi-service container composition.

+===== Module 5. Messaging, Web Services, and Enterprise Integration =====
+This module moves from direct request-response integration toward asynchronous communication, XML-based service standards, and enterprise-scale middleware patterns.
